In this episode, building scientist Dr. Allison Bailes shares his journey from physics academia to the world of building science. He discusses the importance of airtightness in homes, explaining how it directly impacts indoor air quality, comfort, energy efficiency, and moisture control. Bailes challenges the myth that houses need to “breathe,” advocating instead for air-tight construction combined with well-designed ventilation systems.
